LoL: DOCISK vs Forsaken (BO3) - Rift Legends Regular Season

Platform comparison

Market context

Polymarket is pricing the DOCISK side at 0% YES today, which leaves the contract effectively pinned to Forsaken unless late information or a resolution edge case shifts it before the settlement cut-off. The market is for a best-of-three in Rift Legends’ regular season, with the match originally listed for 25 August 2026 at 1:30 pm ET, and payouts settle through Polymarket’s usual USDC-on-Polygon conditional-token structure.

Forsaken entered the matchup as the stronger side in market context, with Polymarket’s own market page describing it as the clear favourite and citing a 3-0 round-robin record and around 75% map win rates, while head-to-head notes point to a 3-0 overall series edge and a 2-0 win in their most recent Spring meeting[2]. That framing matters for a 0% read: on Polymarket, traders are not backing the abstract fixture, but the tokenised outcome that either redeems to USDC on a DOCISK win or expires against it if Forsaken take the series[6][10].

The key catalysts are simple: whether the match has actually been played, whether any postponement lands inside the market’s rescheduling window, and whether an official result is posted before the settlement deadline. GosuGamers listed the series as live on 25 August 2026, which points to a played event rather than a cancellation, but the final resolution still depends on the match status and outcome being settled cleanly within the contract rules[1].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

UK Frequently Asked Questions

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
